APPARATUS FOR DELIVERING AiND DISTRIBUTING MATERIAL To all whom it may concern:

Be it known that I, CHRISTOPHER 'W. LE; VALLEY, a citizen of the United States residing at Milwaukee, in the county of ll- 5. waukee and State of \Visconsin, have in,- vcnted'certain new and useful Improvements in Apparatus for Delivering and Distributing Material, of which the following is a specification. My invention relates to mechanism for distributing material that will flow, and it has been devised with especial reference to being used to deliver mixed concrete in street paving operations; although it is capable of a wide variety of applications and uses. These distributing means include a spout that receives the mixed con crete from a receptacle in which it is contained, such as mixing machine, means for *supporting, directing, and manipulating the spent so that the material shall be delivered at the desired places, and means for directing the material from the receptacle in which it is contained to the spout. In the accompanyin draw1ngs Figure 1 is a side e evation of apparatus embodying my invention. Fig. 2 is a top plan view of the same.

Fig. 3 is a front end view; and Fig. 4 is a detail view in side elevhtion illustrating the parts in a different position from that. represented in Fig. 1,

. In the drawings, 16 indicates a receptacle adapted to, contain the material to be distributed,the specific form of receptacle illustrated being a concrete mixing machine of the rotary type. This is mounted in suit able framework 17 from which; projects a lower bracket 18 and an uppergbracket 19. 4o In these brackets are supported, b'yiivcrtical pivots 21, a swinging frame 22 constructed toform a pair ofchannels 1, 1, that incline upwardly and forwardly, or away from the receptacle 16, a cross'piece 23 uniting the lowor ends of the channel frame pieces 1 with the vlower vertical pivot 21, and a 'Jbracket 24 unitin the u or ends of, the

"channcl frame pieces 1 wit the upper pivot! :25 indicates a spout 'to receive the material 'f'roin' the receptacle 16 and deliver it to the place or laces where it is t be used. The inner en of the spout, that'. the receiving end thereof, is supported imthe frame 22 and is vertically mov ble therein. 5 represent wheels secured the spout and or Specification of Letters Patent.

ranged to travel in the channels formed by the side frame pieces which thus operate to *support and guide the spout in its up and down movements. The outer delivery portion of the spout is supported by a cable, bar, or equivalent tension device, 2, extending from where it. is secured, at 4, inthe upper portion of the frame 22 to a pivoted yoke 3 secured to the spout.

6 represents a cable suitably connected, at 7, with the inner portion of the spout, whence it extends over a sheave 8 sup orted in the bracket 24 of the swingin rame, past. guiding pulleys 26 supporter by the bracket 19, and over a turning and guiding pulley 27 on the framework 17, whence it continues to a drum 9 upon which it is wound. Alongside of the drum 9 and rigidly connectcd therewith is a larger drum 10 upon which is wound a cable 11 that extends to a winding dry n 1'2. loosely supported upon a power sh ft 13 mounted in the framework of the ,machine. A manually controlled clutchliserves as the means for connecting at will the winding drum with the power shaft 13.

It will be seen that whenever the drum 12 is connected with the power shaft the cable 11 is wound thereon and drawn off from the drum 10. which is thereby rotated. The ro- F5 tation of this drum turns with it the drum 9; and causes the cable 6 to be wound on its drum. This lifts the inner end of the spout, giving it an inclination. as indicated in dotted lines in Fig. 1, which may be sufficient to cause the material that has been delivered to it to flow and be discharged at the desired place of use. As the inner end of the spout is thus elevated the spout as a whole turns about the connection of the suspending 6 tension member L. with the spout as a pivot, so that its deliveryend appif aches the surface of the ground whenever material is to be delivered. thus tending to insure a. gentle deposit of the material, which in the case of freshly mixed concrete is very desirable.

- The upward and forward inclination of the iidewaysda which travel the wheels 5 carried by the spout. causes the spout to be carried bodily forward and away froni the receptacle 16. whenever its inner end is elevated so that it clears the end of th delivery chute 15 through which material is directed from the rece tacle 16 to the spout 25, and under which c ute the inner end of the spout l 10 lies when lowered to receiving position. The spout-25 may be formed of separate sections arranged to be brought into alinement with each other and held to form a continucos conveyor, or to have the sections toward the deliver end adjusted to cause a delivery of materia at different distances from the receptacle 16. Thus the spout may have an outer pivoted section 28 that is adapted to be swung upwardly, as indicated in dotted lines in Fig. 1, to s iorten the effective workin length of the spout; and also an intermediate ivoted section 29 which may let down, as a so indicated in dotted lines in Fig. 1, and cause deliver at an intermediate point.

These features 0 spout construction, however, are well known in the art and I lay no claim to having invented them.

It is important that the delivery of material from the receptacle 16 to the receiving end of the spout be controlled, so that whenever the spout is lifted to deliver its charge the supply from the receptacle 16 may be cut off. I therefore preferably interpose between the said receptacle and the inner end of the spout the following delivery-control devices.

indicates a shaft suitably supported in the framework 17 and on which is mounted 30 a'wheel 31 by which the delivery control chute is operated. Keyed to the shaft 30 is a short arm 32 to which is ivotally connected a bent link 33. The link unites the arm 32 with a longer arm 34 extending from 35 a shaft 35 that extends across the machine and carries a pair of arms 36 that are secured fast to the swinging delivery chute 45. The parts connecting the shafts 30 and 35, to wit, the arm 32, the link 33, and the arm 40 34, are so disposed and shaped that when the delivery chute is in the position indicated in full lines in Fi 1, delivering to the spout 25, the pivots 0% the link 33, uniting it respectively with the arms32 and 34, are in line with each other and with the axis of the shaft 30; that is to say, the parts are locked in a dead centerrelationship, so that pressure upon either end of the chute will not tend to disturb the said relationshi or cause the chute to be shifted from its de ivery position. And again, when the arts are adjusted to the position inditcate in Fig. 4, with the chute occupying a mom-delivering or cut-off position, the pivots ofthe link 33 are again in line with the axis of the shaft 30 and hence locked in dead ,center position, so that the chute is again held securely in this position. The arm 32 and link 33 are rovided with contacting parts 37 that ma e the joint uniting these stifi' in one direction, so that a rotation of the operating wheel 30 to turn the chute 45 from deliverv to cut-ofi' position causes a positive movement of the link and the several connected )arts of thcs. dcli\'cl' coutrol devices. The change of position of the chute from delivery to cnt-ofl' position not only stops the delivery of material from the receptacle 16, but also takcs the outcr or projecting end of the chute somcwhnt out of the path of the distributiup, spout 25. It also insures that any drip from the chute shall be carried back into the receptacle when it is turned into cut-ofl, non-delivering,'position. While the form of delivery control devices described and illustrated is that which I prefer, my invention is not limited in its useful applications to the specific devices shown.

By arranging the guide that controls the movements of the inner end of the distributing spout as illustrated such end of the chute is carried bodily away fronrthereceptacle 1G and from any delivery chute that may be associated therewith; and this bod ily movement of the distributing spout might be depended upon alone to clear the delivery chute when the distributing spout is lifted to cause the material to How and be discharged.

The connection between the supporting .tension member 2 and the distributimg spout constitutes a shifting fulcrum about which the spout turns when adjusted upward and downward. such fulcrum both risino' and advancing outward or away from tlie recoptacle l6 when'the inn 1' end of the spout is elevated, but not to tile some extent as tho latter.

lVhat I claim is:

1. The combination witha receptacle for material and a chute dclivoring therefrom, of a spout for delivering the material, the inner end of which is located below the chute to receive material delivered from the said receptacle, and .guides for the inner end of the spout arranged to cause it to move bodily away from the said rcccl'itaclc and from beneath the chute as tliosaid innor end is elevated, and means for elevating the inner end of the spout.

2. The combination with a receptacle for material, of a distributing spout the inner end of which is located so as, to receive material delivered from said receptacle, a frame in which the inner end of the spout is supported having guidewuys for directing its movements, the said guideways extending upwardly and away from the receptacle, means for lifting the inner end of the spout to cause it to assume an inclined position so as to discharge by gravity, and a tension member extending from the upper part of the said frame to the outer portion of the spout for sus ending the latter.
